Abstract (en)
In a lens system (12), an auto-focus (AF) mode switch (50) for selecting an AF mode is provided at a focus demand (28) and, for example, a continuous AF mode is selected by the AF mode switch (50). Then, a CPU (30) switches the continuous AF to a manual focus (MF) when an operation of the focus demand (28) is executed and switches the MF to the continuous AF when an AF start switch (52) provided at the focus demand (28) is turned ON. Thus, when an operation of the MF is executed during focus adjustment by the AF, the focus adjustment by the AF is switched to focus adjustment by the MF, and thereafter, the focus adjustment by the MF is never switched to the focus adjustment by the AF unless the AF start switch (52) is turned ON, and is therefore effective, for example, in the case where an operator wishes to use the AF only for a short time or in the case where an operator wishes to make a camera unfocused intentionally with the MF during the focus adjustment by the AF. <IMAGE>
